AUTOMOBILE-BUMPER.

Application filed ,November 30, 1917.

To all whom. it may concern:

Be it known that I, ABIIAHAMITISMAN,

a citizen of Russia, and residing at New.

York, in the county of New York and State of New'lork, have invented certain new the art to which it appertains to make and use the same.

This invention relates to bumpers or buffers for power driven vehicles, and to devices of this class such as are usually connected with the forwardly directed side extensions of the chassis, and theobject thereof is to provide improved attaching devices for connecting spring bumpers 0r buli'ers with the chassis, each of which consistsof two parts having no spring action and no spring connections. and with one of which the spring bumper or buffer is detachably connected and the other of which is connected with the said side extensions of the chassis, and with this and other objects in.view the invention consists in devices of the class specified, constructed and operating as hereinafiter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part in which the separate parts of my improvement are designated by in each of the Figure 1 is views, and in which: a plan view of the forwardly directed side. extensions of the chassis of an automoblle and showing a spring bumper device connected with the said extensions by my improved attaching devices;

Flg. 2 a'view looking in the direction of ibthemrrowxQ of Fig. -1;

Fig. 3 a section on the line 33 of Fig. 2;

Fig. 4 an inside view of one partfof my improved attaching device or devices:

" Fig. 5 a bottom plan view thereof; and,

Fig. 6 a side view of a clamp hook which I employ.

In the drawing forming part -of this specification. I have. shown at a forwardly directed side extensions of the chassis of an automobile and with which bumpers or bufi'ers of the class under consideration are usually connected, and at b I have shown a spring bumper or buffer which may be of any desired form or construction, but which is provided with parts '6 by means of which Specification of Letters Patent.

suitable reference characters Patented Jan. 21, 1919. Serial No. 204,548.

it is connected with the hereinafter described.

Each of my improved attaching devices 0 consists of two main parts (i and e and two thereof are employed. The parts (1 comprise head portions (Z and arm portions d, and the head portions (1 are L-shaped in cross section and comprise back plates and bottom plates (5, and beneath the back plates are downwardly directed ears cl, and the free end portions of the arms li 'are provided with circular heads (1 having lock teeth (5. 1

The parts 0 of the attaching devices comprise yoke-shaped clamp' members a one attaching devices, as

side of each .of which is provided with a short arm 0 having a head e provided with lock teeth which cooperate with the lock teeth a", and the separate parts (i and c of the attaching devices are connected by bolts f passed through the heads (13 and e and provided with nutsfi. and by means of this construction the parts e of the fastening devices 0 may be adjusted vertically, as

' will be readily understood.

The parts aof the chassis are constructed of channel iron or are U-shaped in cross section and are so placed that the channel therein opens inwardly. In connecting the parts (I of the attaching devices therewith, the heads (I of the said parts are placed, as shown. with the. arms (i on' the outer sides of said extensions and the bottom parts ll of the heads '4 on the bottom thereof. I also provide clamp hooks g having shanks 17 which hooks g are placed so as to engage the bottom flanges ot the extensions a of the chassis and also the bottoms (1" of the heads (1 as clearly shown in Figs. 2 and 3. while the shanks of said hooks g are. passed through the ears e of the heads and nuts 9 are employed in connection therewith. By means of this construction the arms (I of the parts 0 of the attaching devices are securely bound to the outer sides of the forwardly directed extensions a of the chassis. In connecting the spring bumper or butter 12 with the parts 0 of said attaching devices. the parts I) of the. bumper or buffer are dropped into the yoke-shaped clamps ,e where they are secured by means of bolts or screws It passed through the tops or head portions of the sides of theyoke-shaped clamps e With this construction the spring bumper parts be vertically adjusted into different, posi ons, as will be readily understood, and the attaching devices 0 may be quickly and easily connected with the parts a whenever necessary, or desirable, or as quickly and easily.detached therefrom, and

with this improvement, it will be seen that are connected with or buffer may the attaching devices 0 the outer sides of the parts a instead of being mounted on and thereof as is customary, shown and described the parts a with the channels therein opening inwardly, this po sition of said parts may be reversed and the vices with the parts d thereof issimilar to that employed in said prior application, the novel feature in this method of, and means (Z "of the attaching side extensions a of the chassis, as herein shown and described. 7

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is y 1. A bracket device for connecting spring bufl'ers with forwardly directed channeled extensions of the chassis of a vehicle, said device consisting; of two parts detachably and adjustably connected, one of said parts secured to the tops and while I have case being the; for, connecting the devices with the.

comprising an integral arm having an L- shaped head adapted to engage the back and botton of said channeled extensions, said L-shaptul headsbeing provided with downwardly directed lugs having apertures,

clamp hooks mounted in said apertures an adapted to engage the bottom of the chan-I neled extensions to secure said part to the same and the other of said parts comprising.

an arm provided with a yoke-shaped clamp adapted t receive and support a spring bufi'er device. v

A bracket device for connecting spring buffer with forwardly directed channeled extensions of the chassis of! vehicle, sai device consisting of two parts detachably and adjustably connected, one of said parts comprising anintegral arm having an L- shaped head adapted to engage the back and bottom of said channeled extensions, said Lshaped heat comprising a back memher having a countersunk inner face and a bottom member onsi ting of two inwardly directed feet and two downwardly'directed lugs having apertures, clamp hooks mounted in the apertures in said lugs and adapted to engage the bottom of said channeled extensions to secure the other of said parts being adapted to receive and support a spring buffer device.

In testimony that I claim the foregoing as my invention 1 have signed my name in presence of the subscribing witnesses this 28th day .of November, 1917.
